I started to put facebook likes button on my blog last week and my google analytics shows very weird numbers. As you can see from my attached graph, google analytics shows very high pageviews, but when I clicked the link to check detail, it shows for example: 499 pageviews 1 unique views 00:00:08 time on page which is totally impossible for one person to view 499 pages in 8 seconds. What is the problem? I attach two captured graphs, thanks guys.
